Step by Step

Surface preparation 

The surface shall be cleaned thoroughly of all contaminants like dust, traces of curing compound, oil and grease. All surface imperfections, nail head protrusions, structurally unsound and friable concrete shall be removed and repaired with a suit-able Polycrete* concrete repair mortar.

The surface must be dry before priming with Bituprime SB. 


Mix the contents of the pail or drum for a few minutes to remove any sediments. Apply the primer @4-6 m²/L to a clean smooth and dry surface by brush/roller. Allow the primer to dry prior to the application of the membrane. For highly porous surfaces application of a second coat is recommended.
